The NB3N201S and NB3N206S are pure 3.3 V supply differential Multipoint Low Voltage (M-LVDS) line Drivers and Receivers. Devices NB3N201S and NB3N206S are TIA/EIA-899 compliant. NB3N201S offers the Type 1 receiver threshold at 0.0 V. NB3N206S offers the Type 2 receiver threshold at 0.1 V. These devices have Type−1 and Type−2 receivers that detect the bus state with as little as 50 mV of differential input voltage over a common−mode voltage range of −1 V to 3.4 V. The Type−1 receivers have near zero thresholds (±50 mV) and exhibit 25 mV of differential input voltage hysteresis to prevent output oscillations with slowly changing signals or loss of input. Type−2 receivers include an offset threshold to provide a detectable voltage under open−circuit, idle−bus, and other faults conditions. NB3N201S and NB3N206S support Simplex or Half Duplex bus configurations.
